IMPROVEMENT lN WASHING-MACHINES.

Specification forming part of Letters Patent No. 189,319, dated April 10, 1877; application filed February 23, 1877.

To all whom it may concern:

Be it known that 1, DAVID MILLER, of Bellvue, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Washing-Machines; and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in washing-machines of that class in which a corrugated cylinder is arranged to rotate within a boiler; and it consists in the novel construction and combination with the corrugated cylinder of corrugated and convex ends, the same being adjusted to rotate within the boiler, as hereinafter more fully set forth.

In the accompanying drawings, which form part of my specification, Figure l is .a perspective view of the washing-machine. Fig.

2 is a vertical transverse section of the same.

' Fig. 3 is a vertical and longitudinal section the boiler, B the lid, and O the cylinder, all

of which are constructed of tin or other suitable material. The bodyA of the boiler is provided with suitable bearings 00 for the trunnions i of the cylinder 0. The cylinder is constructed of a sheet or sheets of corrugated metal, the corrugations running lengthwise of the cylinder, and furnished with a large number of perforations. The ends 9 g of this cylinder 0 are made convex, with the convexity inward in the cylinder, and with a series of corrugations, g g, which radiate from the center to the circumference thereof. The cylinder is provided with grooves m, in which slides the door D, which door is held closed by means of the hook f. One of the trunnions is provided with a square cavity for the reception of the axis 70 of the crank l, which is used for the purpose of rotating the cylin-.

der 0. The lid B is provided with a funnel,

for the purpose of supplying the boiler with.

water, without the necessity of removing the It will be observed that the trunnions t are secured to the ends 9 of the cylinder by convexing outward a portion of the ends g, and using a convex disk, h, which is secured over the concavity made in the ends 9, so that the space between the disk It and the wall of the end g, in which the trunnions i are secured, will be lozenge-shape when viewed in cross-section.

From the foregoing description, and by reference to the accompanying drawings, the skillful mechanic will readily understand the construction of my improved washing-machine, and the relation that the several parts bear to each other. I will, therefore, proceed to describe its operation.

The clothes to be washed are properly soaked and placed within the cylinder, filling it about two-thirds full. Water is then poured into the body A of the boiler, filling it up to within a short distance of the bearings a. When the water comes to the boilof them to be brought incontact with the corrugated rubbing surface of the cylinder G.

The peculiar form of the outer walls of the ends g of the cylinder, and the tendency of the liquid to travel over the surface of the ends 9, and the ingoing current of air at the opening for the crank caused by the revolving of the cylinder, and the space :0, will-prevent leaking at the opening for the crank Z.

Having thus described my improvement, What I claim as of my invention is In combination with the boiler A, the herein-described washing apparatus, the corrugated cylinder O, having its convex ends 9 9 formed with a series of radial corrugations, and adjusted to rotate within the boiler, substantially as shown and set forth.
